Oversold © 2026
A smarter way to measure how oversold an asset really is.
ZSZscaler, Inc. Common StockXTRM -360RSI is the most popular oversold indicator, but it only captures a single moment in time. A stock that briefly dips below 30 for one day is treated the same as one that's been crushed below 20 for three weeks.
RSI resets every period. It has no memory of what happened yesterday. These are fundamentally different situations — and they require different analysis.
XTRM keeps a running count of how many periods a stock has spent in extreme territory. The longer and deeper the selling pressure, the more negative the XTRM score becomes.
An XTRM score of −200 tells you something RSI never could: this stock has been under extreme selling pressure for an extended period and may be approaching a point of exhaustion — exactly where reversals tend to happen.
The more negative the score, the more extreme the oversold condition.
Entering oversold territory. Selling pressure is building but hasn't been sustained long enough to be significant.
Sustained selling pressure. The stock has been extreme for an extended period. Worth monitoring closely for reversal signals.
Significant and prolonged downward momentum. The selling pressure is extreme and the stock is likely drawing attention from reversal traders.
Point of exhaustion. Historically, these are the setups with the highest probability of producing a meaningful reversal.
